South Central Kansas | A Sequoia has five lenses. One is a Red Green Blue sensor. (essentially the camera in your phone or similar) The other four are designed to only gather reflectance information in specific wavelengths across the light spectrum. I don't own a Sequoia but I think the lenses are set as follows: one for the Red channel one for the Green channel one for the Near Infrared channel and one for the RedEdge channel. I would advise against the gopro. If you're intending on measuring any of the reflectance values, or comparing images of the same crop over time...you can't do that accurately with a gopro. The Incident Light Sensor on the sequoia is there to compensate for imagery taken under various light conditions. That being said, there are lighting conditions where data collection has a high chance of being compromised, even with that sensor. An example would be early morning, later evening and scattered clouds...especially when they're moving quickly. | |

Single band NIR vs 5 band NIR, what is necessary, what is overkill?
